Could a gunsmith explain something to me please?

Well - Are you sure the rounds are chambering smoothly? If there is some obstruction(rust) or defect in the chamber that requires some force to overcome, then you would have a problem. Just take a round and try to insert it in the chamber by hand... BTW - Look at the radial marks on the case wall in your pic...
 
Update!

So here's the deal, I can get all rounds to fire but I have to press forward on the bolt handle every time to make sure it's properly seated. Now this doesn't happen with every round but I do have to check it every time or else it fails.

Happening through the magazine and hand loading it. I tore it apart last night and couldn't really see anything that would be preventing the bolt assembly from not seating properly... My question is, how could I identify what is causing this issue? Like I said, doesn't happen every time and this is with 3 types of ammo, rem, CCI and win.

Have you heard back from Mossberg? Instead of having to mess with accuracy - holding the bolt forward everytime you shoot - Mossberg should make it right especially after a certified Mossberg repair center fugged it up.
 
Yeah, they want me to send it back to the same bird that, get this; didn't check the recoil spring!

My shims worked! 10 on 10 fired. What a fiasco! I cut 4 tiny washers, installed them, went out to my favorite bush spot and shot 10 rounds no issue! I can't believe this! I was happy and also angry that something as simple as a spring was overlooked by this so called gun smith. He tried to blame my magazines and i honestly don't think he even test fired it because how could he have got 50 rounds to fire successfully with this spring not getting the bolt face seated properly? Mind boggling... The audible click I was hearing when pushing forward was the extractor finally gripping the rim.

Unbelievable...

On that note, I am relatively happy now. I don't know how long my shims will work for, I opted to replace the washers with a spent brass casing I cut with my brass cutter and I think although it's a soft alloy, it'll hold up until they either send me a new spring or I buy one, which I shouldn't have to...

Mossberg USA distributor will send you Springs for free if you have an American shipping address. They sent me two to my USA address. Or you can pay ~20$ for one.
 
That is excessive headspace... a correctly fitted rim fire bolt should not move forward when in the closed position.

But it it possible that because of the spring lacking tension, it wasn't fully seated? The bird that recut the chamber said he put gauges in and it's fine... Here's what he said: Not possible to change head space since gun is always head space after reaming.

Regardless, these shims are working and it's firing consistently! I know I won't be buying another rifle from Mossberg, maybe a shotgun but at this point, I don't think it's in the foreseeable future!

Rim fire bolts have a recess that the rim of the case fits in... this recess is what controls the 'headspace'. The bolt is to be fitted so it contacts the back of the barrel. If the front of the bolt does not contact the barrel when fully closed, without pushing it forward, you have a slight headspace problem. The more you can move the closed bolt forward, the more headspace you have... excessive headspace is the biggest cause of rim fire misfires. I surmised from your earlier posts the bolt had been altered so it would close easier. This is usually done by removing metal from the part of the bolt handle that locks the bolt when closed. Removing this metal increases effective 'headspace'.

Do what you want. This has been flogged to death. I have no more to say...
 
Guntech, I appreciate everything you've said and pointed out as I have everyone else. I came here for help and you have helped identify the problem.

Mossberg's idea of rectifying the situation does not really do anything for me because grech has been nothing but problematic. The cost of me shipping it there, insured, just doesn't work for me on top of the long wait. And I highly doubt they will actually do anything to fix it given they didn't the first time.

As I said, I truly appreciate your knowledge and help on the matter! You and everyone else makes this community a great place.

I would want to send it back to gretch, but not on my dime. Im assuming it was on your dime the first time? They should have fixed this issue the first time, and if they returned a still-faulty gun to you, they should foot the bill to ship it back. Furthermore, they modified your rifle (which probably hurts your resale because of the sloppy bolt handle now) and that didn't even fix it. Hell, I'd be asking for a new rifle that hadn't been melosted my an incompetent smith. I would also be asking mossberg to review their warranty centers, because this one is obviously not up to the job.
 
Yeah I'm looking at 80% of the cost of the firearm in shipping and insurance alone, hence why I don't want to send it back. They haven't offered anything but apologies.

I don't know if it's because I got some bad reps or they simply don't know enough about firearms. The thing is, I would love a new one but i don't see that happening unfortunately. I bet if I was in the states it would be different but it's not the case.

I have asked them to review their service center and I also mentioned the lack of communication and empathy as well as general customer service from this company Grech. It's been a headache to say the least. They said they fixed it 2 days after receiving it and was shipping out only to be shipped out 10 days later and I had to drive 2 hours, there and back, to go pick it up. So fuel, shipping, wasted time and ammo... I just refuse to send it back to them. I really don't feel like wasting my time anymore. Yeah, it's a crummy cheap gun but as others have said, it should go boom every time. It is now thanks to my fix and I will just be looking for a better 22, probably a 10/22 or maybe even a 597 or savage.

I'm wondering though, if there was excessive headspace, how come the bolt would move? On a rimfire, isn't the headspace set purely by the depth of the recess in the bolt face? If the depth is too great, then headspace is too great and the case head isn't pushed right up against the bolt face. But the bolt shouldn't move forward since it's contacting the barrel face. No?
 
As for Grech, they were horrible to deal with for me too. I needed s replacement savage bolt for a center fire rifle.

I ended up getting so frustrated with the answers they gave that I called savage and demanded they send me a new bolt body and that I'd install it myself. Signed a release form, got the body, installed it and confirmed headspace was correct, and merrily on my way having left Grech in the dust ;)

Grech sounds like a really nice place to leave your hard earned money.
 
It's just frustrating how I can be told 50 rounds fired successfully yet when I shoot it, it fails immediately. Maybe it's the luck of the Irish, or lack thereof.

Sounds a lot like the scenario where I took in a CZ 455 to Grech with a bunch of targets that looked like this:



Nearly pushing 3" groups at 50 yards from a bench! With Center-x no less, obviously a problem over 70% of the groups fail CZ's 1" accuracy standard. Grech calls me back the next day after I dropped it off and said its ready. Tells me they adjusted headspace and show me two "passed" targets of 1" and 3/4" groups (each group cut out from the main paper it was shot on). As you can see in my target, 3 "passed" groups were shot I think all they did was shoot enough groups to cut out the passing ones neatly hiding the fact it was still shooting terribly.

Sure enough I go shooting again and it is shooting no different. I go back to them but this time with more evidence, I bought a borescope and found burrs on all the lands in the chamber which in comparison to the 8 other rifles in my safe clearly looks defective. I take pictures and bring another failing target.





When I get there and explain whats going on they tell me "It's a factory barrel, they're all like that! CZ won't replace it." You've gotta be kidding me? It fails the accuracy test and has a proven defect! I argue to get them to send an email of the borescope pics to CZ and I leave. I get an email several hours later that CZ won't replace the barrel so I go pick up my rifle. Verbally they tell me "Defects which require the use of optical devices to observe are not covered under warranty." They refuse to copy me this written statement from CZ.

I'm SOL on a proven defective barrel that should have been replaced no hesitation and Grech failed to support me in that. Heck, they even failed to diagnose the issue. They have a borescope in the shop and never bothered to check (but according to them "they're all like that!") so they can't even recognize a problem. Seems like a very shady operation going on over there, people would be better off not to even bother sending anything to them for warranty. Save the hassle and expense just to find yourself left high and dry.
